1. Any canine pet that you, specifically, can drop-kick over a picket fence, such as a chihuahua or teacup poodle if you are a normal sized person. Andre the Giant could probably kick a mastiff over a fence so every dog would be a rogdat.

2. Any dog that also happens to resemble a rat.

1. Adam: Look at that tiny dog that looks like it could be easily kicked.

Steve: Oh you mean the rogdat?
Adam: What?
Steve: It is to small to be a dog but to big to be a rat, so, rogdat!

2. Bill: Look at that cute chihuahua!
Ted: It looks more like rogdat to me.
